Safety instruction, Warning & Notes

Safety instruction

1. General safety

Safety regulations require that during a repair:

. Connect the unit to the mains via an isolation transformer.

. Replace safety components indicated by the symbol

only by components identical to the original ones. Any

other component substitution (other than original type)

may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, you must

return the unit in its original condition. Pay, in particular,

attention to the following points:

. Route the wires/cables correctly, and fix them with the

mounted cable clamps.

. Check the insulation of the mains lead for external

damage.

. Check the electrical DC resistance between the mains

plug and the secondary side:

1) Unplug the mains cord, and connect a wire between

the two pins of the mains plug.

2) Set the mains switch the “on” position (keep the

mains cord unplug).

3) Measure the resistance value between the mains

plug and the front panel, controls, and chassis

bottom.

4) Repair or correct unit when the resistance

measurement is less than 1M

5) Verify this, before you return the unit to the

customer/user (ref. UL-standard no. 1492).

6) Switch the unit “off”, and remove the wire between

the two pins of the mains plug.

¡

.

2.Laser safety

This unit employs a laser. Only qualified service personnel

,

may remove the cover, or attempt to service this device

(due to possible eye injury).

Laser device unit

Type : Semiconductor laser GaAlAs

Wavelength : 650nm (DVD)

: 780nm (VCD/CD)

Output power : 7mW (DVD)

: 10mW (DVD /CD)

Beam divergence: 60 degree

Note: Use of controls or adjustments or performance of

procedure other than those specified herein, may result in

hazardous radiation exposure. Avoid direct exposure to

beam.

Warning

1-12

1.General

. All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD). Careless handing during

repair can reduce life drastically. Make sure that, during

repair, you are at the same potential as the mass of the

set by a wristband with resistance. Keep components and

tools at this same potential. Available ESD protection

equipment:

1) Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable)

4822 310 10671.

2) Wristband tester 4822 344 13999.

. Be careful during measurements in the live voltage

section. The primary side of the power supply , including

the heat sink, carries live mains voltage when you

connect the player to the mains (even when the player is

“off”!). It is possible to touch copper tracks and/or

components in this unshielded primary area, when you

service the player. Service personnel must take

precautions to prevent touching this area or components

in this area. A “lighting stroke” and a stripe-marked

printing on the printed wiring board, indicate the primary

side of the power supply.

. Never replace modules, or components, while the unit is

“on”.

2. Laser

. The use of optical instruments with this product, will

increase eye hazard.

. Only qualified service personnel may remove the cover

or attempt to service this device, due to possible eye

injury.

. Repair handing should take place as much as possible

with a disc loaded inside the player.

. Text below is placed inside the unit, on the laser cover

shield:

CAUTION: VISIBLE AND INVISIBLE LASER

RADIATION WHEN OPEN, AVOID EXPOSURE

TO BEAM.

Notes

Lead-Free requirement for service

1-14

INDENTIFICATION:

Regardless of special logo (not always indicated)

One must treat all sets from 1.1.2005 onwards, according
next rules.

Important note: In fact also products a little older can also
be treated in this way as long as you avoid mixing
solder-alloys (leaded/ lead-free). So best to always use
SAC305 and the higher temperatures belong to this.

Due to lead-free technology some rules have to be
respected by the workshop during a repair:

x Use only lead-free solder alloy Philips SAC305 with

order code 0622 149 00106. If lead-free solder-paste is

required, please contact the manufacturer of your

solder-equipment. In general use of solder-paste within

workshops should be avoided because paste is not easy

to store and to handle.

x Use only adequate solder tools applicable for lead-free

solder alloy. The solder tool must be able

o To reach at least a solder-temperature of 400°C,

o To stabilize the adjusted temperature at the

solder-tip

o To exchange solder-tips for different applications.

x Adjust your solder tool so that a temperature around

360°C

– 380°C is reached and stabilized at the solder

joint. Heating-time of the solder-joint should not exceed

~ 4 sec. Avoid temperatures above 400°C otherwise

wear-out of tips will rise drastically and flux-fluid will be

destroyed. To avoid wear-out of tips switch off un-used

equipment, or reduce heat.

x Mix of lead-free solder alloy / parts with leaded solder

alloy / parts is possible but PHILIPS recommends

strongly to avoid mixed

solder alloy types (leaded and lead-free). If one cannot

avoid, clean carefully the

solder-joint from old solder alloy and re-solder with new

solder alloy (SAC305).

x Use only original spare-parts listed in the

Service-Manuals. Not listed standard-material

(commodities) has to be purchased at external

companies.

x Special information for BGA-ICs:

- always use the 12nc-recognizable soldering

temperature profile of the specific BGA (for

de-soldering always use highest lead-free

temperature profile, in case of doubt)

- lead free BGA-ICs will be delivered in so-called

‘dry-packaging’ (sealed pack including a silica gel

pack) to protect the IC against moisture. After

opening, dependent of MSL-level seen on

indicator-label in the bag, the BGA-IC possibly

still has to be baked dry. This will be

communicated via AYS-website.

Do not re-use BGAs at all.

x For sets produced before 1.1.2005, containing

leaded soldering-tin and components, all needed

spare-parts will be available till the end of the

service-period. For repair of such sets nothing

changes.

x On our website:

www.atyourservice.ce.Philips.com

You find more information to:

BGA-de-/soldering (+ baking instructions)

Heating-profiles of BGAs and other ICs used in

Philips-sets

You will find this and more technical information

within the “magazine”, chapter “workshop news”.

For additional questions please contact your local
